Application filed March 2, 1920. SerialNo. 362,872.

To all whom it may concern:

Be it known that I, MARTIN CHRISTENSEN, a citizen of the UnitedStates, andresident of Racine, in the county of Racine and State of \Visconsin, have invented new "and useful Improvements in Signature-Conveyer Supports, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. 1 p

The present invention relates to certain new and useful improvements in signature handling machines and refers more particularly to the means for supporting the conveyer. a

In signature machines, the signatures are straddled over the saddle conveyer and are thus presented to I the mechanism, and considerable trouble has been caused with former devices in that the leaves sway back and forth and oftentimes become folded under each other and are thus Hence with the above inherent objections,

in mind, my invention has for its primary object to provide means for preventing this disalignment of the signatures and to straighten out any folds which may be formed in the signatures due to such swaying movement. p

A more specific object of this invention is to provide a novel form of signature conveyer guide support so constructed as to perform the double function of supporting the conveyer guide and providing means for preventing the disalignment of the signatures.

With the above andother objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that stitcher-feeding so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a perspective view of a por tion of a signature conveyer, a conveyer guide and guide supports embodying my invention.

Figure 2 is a perspective view of the lower portion or vertical supporting standard for my improved support, and I Figure 3 is a perspective view, parts being broken away and in section, of the upper portion or inclinedarm of my improved support. v

Referring now more particularly to the accompanying drawing, the numeral 5 designates aguide'niember which maybe of any desired constructionibut in the present instance is channeled and "has disposed therein the sprocket chain" (not shown) of an endless saddle signature conveyer 6, the guide 5 being supported by one or more supporting standards 7, to be later described. 8 designates a tubular guard through which the lower portion of the conveyer 6 travels, and 9 designates a brace rod secured to each supporting standard and connecting the same with the signature machine proper (not shown). I

My improved support consists of two parts, a lower vertical standard 10 and an upper arm 11 having its lower end 12 secured to a securing portion 13 formed on top of the vertical standard 10 and its other intermediate transverse brace 16 providing 7 a support upon which rests the conveyer guard 8. The transverse brace 16 has a centrally bored enlargement 17 formed on its under side intermediate of the supportinglegs 15 for receiving the brace rod 9.

The upper portion or arm '11 of the supporting standard is inclined upwardly and oppositely to the normal direction of movement ofthe upper half of the conveyer 6 as depicted by arrow 18, see Figure 1. The arm 11 being inclined in a direction opposed to the direction of movement of the signature conveyer 6, and consequently of signatures 19 being conveyed thereon, serves as a straightening cam for the levers of the signatures to prevent them from being tolded upon themselves and consequently thrown out of proper alignment, as will be obvious.

Theinclination of the arm 11 is-such that its extreme upper end first engages the signatures 19 juxtapose their folds 20 and as they advance in the direction of the arrow 18, thearm 11 gradually straightens out any folds or irregularities therein, by reason of its inclination upwardly against the normal direction of movement oi? the conveyer 6 and signatures 19 mounted thereon.

From the foregoing description taken in connection with the accompanying drawing it will be at once apparent to those skilled in the art to which an invention of this character appertains that I have provided an improved conveyer guide support which serves as means for preventing the disalignment of the signatures mounted on the conveyer, and which improved support is capable of production at a cost no greater than the supports new in general use. IVhat I claim as IllyiIlVBIltiOIl is: 1. In a signature conveyer, a conveyer support inclined in a direction opposite to a the direction of movement of the conveyer,

and positioned to engage the signature leaves carried by said conveyor.

2. In a signature-conveyer, a conveyer guide, a conveyer movable along the guide, and means adjacent the conveyer guide for engaging signature leaves carried by the conveyer to prevent theirbecoming-turned under. Y

3. In a signature conveyer, a eonveyer guide, a conveyer movable along the guide, and a support for the conveyer guide includ ing an arm secured to the guide and inclined downwardlytherefrom in the direction of the normal movement of the eonveyer, whereby the leaves of signatures being eonveyed by the conveyer will be prevented from becoming folded under, the inclination of the arm functioning as a leaf straightening cam.

In a signature conveyer, a eonveyer guide, a conveyermovable along the guide, and a support for the conveyer guide. in eluding a lower portion adapted for securing to a supporting base and an upwardly extending arm inclined in a direction opposite to the normal direction of movement of the oonveyer and having means on its extreme upper end for securement to the conveyer guide.
